| The
table is the large flat facet on the
crown or top of a diamond. The table
directly affects scintillation, or sparkle
in a diamond. The combination of table
size and crown angle governs the balance
between brilliance, flashes of white
light returning to the eye from within
the diamond, and dispersion, the play
of spectral colors seen by the eye created
by refracted light as it prisms through
a diamond's facets. |

Heart shape table percentages that measure
66% or less are considered to be very fine.
GIA has not established ideal table measurement
percentages for heart shape diamonds, but
heart shape diamonds that have table percentages
below 66% have consistently proven to to
deliver greater brilliance. The brilliance
of your diamond depends on proper cutting.
Our Certified Gemologist-Appraisers select
only ideal to premium cut diamonds to ensure
that the diamond you choose will be as brilliant
as it is beautiful. A diamond with these
premium proportions will cost more, but
its brilliance is well worth the added investment.
